Differential rotation on both components of the pre main-sequence binary system HD 155555
N. J. Dunstone, G. A. J. Hussain, A. Collier Cameron +5
We present the first measurements of surface differential rotation on a pre-main sequence binary system. Using intensity (Stokes I) and circularly polarised (Stokes V) timeseries s…
The first magnetic maps of a pre-main sequence binary star system - HD 155555
N. J. Dunstone, G. A. J. Hussain, A. Collier Cameron +5
We present the first maps of the surface magnetic fields of a pre-main sequence binary system. Spectropolarimetric observations of the young, 18 Myr, HD 155555 (V824 Ara, G5IV + K0…
Magnetospheric accretion on the T Tauri star BP Tauri
J. F. Donati, M. M. Jardine, S. G. Gregory +15
From observations collected with the ESPaDOnS and NARVAL spectropolarimeters, we report the detection of Zeeman signatures on the classical T Tauri star BP Tau. Circular polarisati…
Why are some A stars magnetic, while most are not?
G. A. Wade, J. Silvester, K. Bale +21
A small fraction of intermediate-mass main sequence (A and B type) stars have strong, organised magnetic fields. The large majority of such stars, however, show no evidence for mag…
Weak magnetic fields in Ap/Bp stars: Evidence for a dipole field lower limit and a tentative interpretation of the magnetic dichotomy
M. Auriere, G. A. Wade, J. Silvester +22
We have investigated a sample of 28 well-known spectroscopically-identified magnetic Ap/Bp stars, with weak, poorly-determined or previously undetected magnetic fields, with the ai…
Large-scale magnetic field of the G8 dwarf xi Bootis A
P. Petit, J. -F. Donati, M. Auriere +7
We investigate the magnetic geometry of the active G8 dwarf xi Bootis A, from spectropolarimetric observations obtained in 2003 with the MuSiCoS echelle spectropolarimeter at the T…
